A valid license is compatible with the previous and coming product versions according to the formula «-1/+3»For example, if you have an activation code for a product of 2010 version, using the code you can activate the product of 2009 version or any of three next versions (2011, 2012, and 2013).Licensing
This could be your problem?

That's right! that 2015 code should activate a 2018 version as maximum...
